FRANK J. BERNARD, OF JERSEY CITY, ASSIGNORJBY DIRECT AND MESNEASSIGNMENTS, TO THE AMERICAN MUSIC BOX COMPANY, OF WEST NEW YORK, NEWJERSEY.

MUSIC-BOX REGULATOR.

SPECIFICATION forming part of Letters Patent No. 554,906, dated February18, 1896.

Application filed May 9, 1895. Serial No. 5 18,785- (No model.)

T at whom it may concern.-

Be it known that I, FRANK J. BERNARD, a citizen of the United States,and a resident of Jersey City, county of Hudson, and State of NewJersey, have invented a new and useful Improvement in Music-Boxes, ofwhich the following is a specification.

The object of this invention consists in furnishing a music-box with acheap and efiect- IO ive regulator.

The invention consists in forming from a thin piece of metal a regulatorfor a musicbox.

Figure 1 is the regulator before folding.

Fig. 2 is a side view of Fig. 1. Fig. 3 shows the regulator when folded.Fig. 4: shows the expansion of the wings when in use, and Fig. 5, showsthe regulator as applied to a musicbox to govern the speed of theseveral gears and pinions.

A in Figs. 1 and 2 represents a thin spring metallic strip or othersuitable material.

B B, Fig. 1, represent recesses formed by cutting the metal at b b andbending the cut part B down, while the metal B is pressed in an oppositedirection, which forms a central recess B, Fig. 2, through which thewormarbor C is passed, as shown in Fig. 3. The strips A are then formedlike the letter N by 0 following the metal on lines a: a, one end beingfolded to the right and the other folded to the left, forming wings A Aand a center section A, as shown in Figs. 3 and 4':- The ends of thesewings extend beyond the center sectionA", as shown in Fig. 3, whichcatch the air when rotated in the line of the arrow, causing them tospread, as shown in Fig. 4.

E, E, F and I, Fig. 5, are gears and pinions (forming the drivingmechanism of a music-box) mounted on the arbors E F and I, which aredriven by the springs H secured to the case F by screws H for rotatingthe pressure-rolls K and L and note-sheet N.

J, Fig. 5, is a section of the music-box frame having jewel-cap J heldin place by the screw. This frame supports the arbor C, which isprovided with the worm-threads C, having the usual spring check-lever Dheld in place by the flanges D D. To this worm-arbor I secure myimproved regulator, which governs the speed of the gears and pinions bythe overlapping wings catching the air more or less during the unwindingof the spring from first to last.

While I have shown and described the wings A as approximately parallelto the central section, I do not limit the construction to this form, asthe wings may be parallel to the central section.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

A regulator-vane comprising a straight central section and the parallelright and left wings extending beyond the central section, said Vaneformed of an integral sheet of metal, as and for the purpose described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 29th day of April, 1895.

FRANK J. BERNARD.
